The Teletronix Story
Teletronix founder Jim Lawrence first used photocells for controlling audio gain in the early 1960s. His ingenious optical compression design was a technological breakthrough, far surpassing the stability and transparency of earlier circuits. Universal Audio founder M.T. ”Bill” Putnam later purchased this patented technology, continuing to manufacture the LA-2A for years to come.

The Real Deal
Universal Audio’s Teletronix LA-2A Classic Leveling Amplifier reissue provides the performance characteristics of the iconic original. With painstaking care, every new LA-2A unit is point-to-point handwired at Universal Audio's Custom Shop in Santa Cruz, California, with every component carefully evaluated for authenticity. As a result, today’s LA-2A will bring the same legendary compression characteristics of the original to all of your recordings. Demand the original.

What We Think

The Universal Audio LA-2A is indisputable king of vocal compressor/limiters because of how it just does everything it is supposed to do in reeling in the dynamic range of a vocal. It never sucks the life out of the vocal to accomplish the end result, which also makes it a regular treatment for bass guitars and select electric guitar tracks. The now cliche' terms "fat" and "warm" seem to have been invented solely to describe the character of this legendary piece. Between the LA-2A and UA's 1176LN, I really cannot think of any other gear more indispensable to achieving great sound - period. Of course you can make records without Universal Audio equipment... but why on Earth would you ever want to?

    Amazing on vocals

    Super transparent. Vocals and bass sound SO good through this thing.

    What a legend

    Needless to say, one of the best opto compressors of all time. It makes sound silky, sweet and come alive, and I prefer this gear as a limiter rather than a compressor.

    What is there to say? I'm just another testament to this tried and true compressor/limiter. Throw on vocals and bass and you cannot go wrong. Smooth, silky, perfect.

    A legendary industry-standard compressor!

    This limiter/compressor puts a silky smooth sheen on vocals like no other! If you want to emphasize the breath on vocals like on Kelly Clarkson's "Already Gone", for example, this device will do that. I haven't used it for bass yet, but I hear it works great for that, too.
